Pins are labeled with the number of the pin, followed by the descriptive name used in Chapter 5 of What is your TNC doing? FSK is discussed in the article Which Jack for HF Radio-to-TNC Cables?

Pin 13 - External Carrier Detect (optional)

Note: If you use FSK with the IC-706, see the manual for setting the radio's tone, shift, and keying polarity.

Tip: The pins on this connector are very close together therefore difficult to solder. To make it easier, remove unneeded pins from the connector before soldering.
